  • Revision 5e935126a6 : Add intra complexity and brightness weight to first pass. The aim of this patch

    4 novembre 2014, par Paul Wilkins

    Changed Paths :
     Modify /vp9/encoder/vp9_firstpass.c


     Modify /vp9/encoder/vp9_firstpass.h



    Add intra complexity and brightness weight to first pass.

    The aim of this patch is to apply a positive weighting to
    frames that have a significant number of blocks that are
    of low spatial complexity and are dark. The rationale behind
    this is that artifacts tend to be more visible in such frames.

    In this patch the weight is only applied in regard to the distribution
    of bits between frames. Hence if all the frames share similar
    characteristics (as is the case for most of our short test clips) there
    will be little or no net effect.

    However, the effect can be seen on some longer form test content.

    For example Tears of steel baseline test :
    2323.09 Kbit/s opsnr 39.915 ssim 74.729
    With this patch :-
    2213.34 Kbit/s opsnr 39.963 ssim 74.808
    (Sligtly better metrics and about 5% smaller)

    The weighting may well need some further tuning along side changes
    to the aq modes.

  • dv : fix weight table for 2x4x8 transform

    dv : fix weight table for 2x4x8 transform

    The coefficients must be in the appropriate zigzag scan order.
    
Also fix their values at the same time, as they were pretty wrong.
    

    Fixes ticket #2970.

  • dv : more precise weight table for 8x8

    dv : more precise weight table for 8x8

    It is derived from the actual equations of the specs. In
    
particular, it is closer to the inverse of what the encoder uses.
    

    fate tests accordingly updated.
